neon steer Zinn leaf-roi Applica-.tion ifilerl September le itl" mnftliatq, Minitrue ifi. .Gnnnrrna citizen of -the United States, `residing at Philadelphia, in `fthe coiintyo,f Philadelphia .en nsfylitania, that@ invented certain lnew and Auseful Improvements .in Door :Stops iandatches; 2and zLdo Ihereby declare the following to ,be iaffu11clear,iand exact 'description Ioi .the invention, such as will enable others skilled in the artto which it appertains to makeaandiusethe same.

The present invention ,has for its object the provision of a device whereby to prevent injury to a wall by impact of a door knob or key therewith when the door is swung open and to engage and hold the door in open position and prevent its closing by a draft of air or a slight knock or jolt thereagainst.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure l is a top plan view of the device, the parts being separated, a

Figure 2 is a central, longitudinal section thereof,

Figure l is a side view partly in section with the members partly engaged,

Figure 4 is a view similar to Figure 3, the members being in full engagement, and

Figure 5 is a detail view in perspective of the locking dog.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The device comprises complemental memn bers 1 and 2, each having a base plate whereby it may be attached to the door and surbase or like part, as required. r1`he member 1 is in the nature of a. plunger and is provided in its outer end with a slot 3 in which is located a dog 4 mounted upon a pivot 5. The inner or tail end of the dog 4 is oppositely tapered and its outer end is offset and terminates in a forwardly disposed beak 6. The offset portion 7 of the dog is adapted 8, i923. Serial No. @6,15597.

to project lateigally beyond va side of ythe member l. to engage a stop shoulder of the member 2 and look the vtwo .members and hold the door yopen position.y

.The member 2 consists ,of a cylinder or .bai-,rel having its vouter `,if'iortion `constricted to snugly receive the member l and to pro- .vide ,an innerannular .shoulder `8 .to `engage the Llaterally l.projecting offset .portion 7 of. the dog 4'. A .pressure plug :9 slidably mounted within themember 2, has its outer or fo ard ,end beveled, as indicatedat l0, and its inner or rear end recessed to receive one end of a helical spring 11 disposed with-in the men'iber 2 and held in place by means of a pin 12. The helical spring 11 normally exerts a pressure to urge the plug 9 forwardly, whereby to yielda-bly engage the offset portion T of the dog 4 and hold the projecting end thereof in engagement with the stop shoulder 8. The beak 6 of the dog 4 engages the beveled portion 10 of the pressure plug 9 and is adapted to ride thereon when a suiiicient force is exerted to withdraw the member l from the member 2. 1n this case, the dog 4 turns upon the pivot 5 and the plunger 9 is pressed inwardly against the tension of the spring l1 until the projecting portion of the dog clears the shoulder 8, when the door may be closed.

In practice, either one of the members may be attached to the door and the other to the surbase or wall, the parts being so arranged that upon opening the door, the member l enters the member 2. r1he spring pressed plunger 9 acts as a buffer to miniinize the impact and also operates to hold the dog 4 with its laterally projecting end in engagement with the stop shoulder 8. To close the door, sufficient force must be ei:- eited to withdraw the member l from the member 2 and this can be eiifected only by a riding of the beak 6 upon-the beveled end i0 of the plunger 9. It will thus be understood that a draft of air or a slight knock against the door will not operate to close the same.

What is claimed is:

l. A combined door stop and catch coinprising complementary members, the one consisting of a barrel and the other a plunger, a dog carried by the plunger and adapted to engage a fixed shoulder within the said barrel, and a spring pressed plunger within the barrel arranged to engage said dog and operating as a buffer and also acting to norina-lly hold the said dog in enga-gement with the stop shoulder of the barrel.

2. A combined door stop and catch coniprising a barrel having an inner stop shoulder, a plunger, a dog carried by the plunger and adapted to engage the stopshoulder of the barrel, and a spring pressed plunger within the barrel and adapted to Cooperate with the said vdog and plunger and having a beveled portion for the projecting end of the dog to ride upon.

3. A levice v'of fthe character specified, comprising a barrel having an inner annular shoulder.y a spring actuated plunger within the barrel having its forward end beveled, a

plunger adapted to enter the barrel, and a dog pivoted to the plunger to one side of a Central line and having a laterally disposed offset portion adapted to engage the annular shoulder of the barrel and terminating in a forwardly disposed beak adapted to engage and ride upon the beveled end of thev prising a barrel having an inner annular shoulder, a spring actuated vplunger within the barrel having its forward end beveled, a slotted plunger adapted to enter the barrel, and a dog p'ivoted within the slot of the plunger and comprising a tapered tail end, a laterally offset portion and a forwardly disposed beak, the latter adapted to engage and ride upon the beveled end of the spring actuated plunger and the projecting part of the laterally offset portion adapted to engage the inner annular shoulder of the barrel.

In testimony whereof l aliix iny signature in presence, of two witnesses.
